On October 9, 2013, Wilshire Bank, the wholly-owned subsidiary of Wilshire Bancorp, Inc. (the “Company”), received notice from the California Department of Business Oversight (the “DBO”) that effective September 30, 2013 the DBO approved Wilshire Bank’s proposal to merge with Saehan Bank, the wholly-owned subsidiary bank of Saehan Bancorp (“Saehan”), with Wilshire Bank surviving the merger (the “Bank Merger”).  The Bank Merger is to be consummated immediately after the merger of Saehan with and into WS Merger Acquisition Corp., a wholly-owned subsidiary of the Company (“Newco”), with Newco surviving the merger (the “Merger”), pursuant to the Agreement and Plan of Merger and Reorganization between the Company, Newco and Saehan, dated as of July 15, 2013 (the “Merger Agreement”).  As the Company previously received the necessary regulatory approvals for the Merger and the Bank Merger from each of the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation on September 26, 2013 and September 25, 2013, respectively, all bank regulatory approvals required in connection with the Merger and the Bank Merger have now been obtained.

Completion of the Merger remains subject to approval by shareholders of Saehan of the Merger Agreement, as well as to other customary closing conditions.

On October 15, 2013, the Company issued a press release announcing the receipt of all necessary bank regulatory approvals for the Transaction, a copy of which is attached hereto as Exhibit 99.1.
